/*
 * Themed to match the portfolio's neo-brutalist design system
 * (thick borders, hard offset shadows, Space Grotesk/Mono, yellow/cyan/pink
 * accents). Reads the site's own CSS variables where available (--bg,
 * --text, --border, --primary, --secondary, --white, --shadow-offset,
 * --border-width) and falls back to the same palette's literal values on
 * pages that don't define them, so the widget still looks right everywhere.
